| Detailed Description |
The version of OpenSSL installed on the remote host is prior to 3.0.3. It is, therefore, affected by multiple vulnerabilities as referenced in the 3.0.3 advisory.
- The OPENSSL_LH_flush() function, which empties a hash table, contains a bug that breaks reuse of the memory occuppied by the removed hash table entries. (CVE-2022-1473)
- The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. (CVE-2022-1434)
- The function `OCSP_basic_verify` verifies the signer certificate on an OCSP response. In the case where the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful verification) even in the case where the response signing certificate fails to verify. It is anticipated that most users of `OCSP_basic_verify` will not use the OCSP_NOCHECKS flag. In this case the `OCSP_basic_verify` function will return a negative value (indicating a fatal error) in the case of a certificate verification failure. The normal expected return value in this case would be 0. This issue also impacts the command line OpenSSL ocsp application. When verifying an ocsp response with the -no_cert_checks option the command line application will report that the verification is successful even though it has in fact failed. In this case the incorrect successful response will also be accompanied by error messages showing the failure and contradicting the apparently successful result. Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). (CVE-2022-1343)
- The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. (CVE-2022-1292)
